ZOlalml.

My invention relates to improvements in wrenches and has as one of the principal objects thereof the provision of a wrench equipped with means operable for engagement with a pair of threaded elements whereby to secure one of said elements stationary while the other of said elements is actuated for adjustment, attachment or detachment relative to the first element.

Another object of my invention is to provide a wrench ofthe character described equipped with means for reliably securing one of a pair of nuts stationary while the other nut is adjusted relative thereto and which means is simple in construction, durable in use, eiiicient in operation and economical in manufacture.

Other objects and advantages will/be apparent from the following description. appended claims and annexed drawing.

Referring to the drawing wherein like reference characters designate like parts throughout the several views:

Figure 1 is a side elevation of my invention.

Figure 2 is a sectional View taken on the line 2-2 of Figure 1.

Figure 3 is an end elevation of the detachable head member.

Figure 4 is a sectional view taken on the line 4-4 of Figure 2.

Figure 5 is a side elevation of the head member.

In practicing my invention I provide a wrench 5 comprising a barrel Ii formed with a longitudinally extending bore 1, the ends of said bore being formed with oppositely disposed conical shaped countersinlas 8 provided with lengthwise extending grooves 9. The outer ends of the barrel B are formed with enlarged sections I0 of hexagonal configuration in transverse section whereby the faces thereof are 'adapted for engagement with the jaws of a wrench or other similar tool for a purpose hereinafter more fully set forth.

A cylindrical shaped head member I I is provided for association with one end' of the barrel and comprises a body section I2 fashioned with a conical shaped shank I3 formed with lengthwise extending teeth I4 seating within the grooves 9 whereby to preclude rotation of said head relative to said barrel. The opposite end of the body I2 is fashioned with an enlarged section I5 formed therein with a hexagonal socket I6 which communicates with a cylindrical shaped socket I'l of a lesser diameter formed within the body section I2. The shank I3 is formed with a bore I3 communicating with the socket I1 and of a lesser diameter than the latter to provide a shoulder or seat I9.

A pry or lever 20 of a substantially elongated cylindrical configuration is detachably and rotatably secured within the bore 1 and is fashioned at one end with a cylindrical shaped head 2l seated within the socket I'l and having an inwardly disposed face abutting the shoulder I9. salfhead 2| 1s fashioned with a square shaped socket 22. 'Ihe opposite end of the lever 20 extends an appreciable distance beyond the end of the barrel and is formed with an arcuate cuneiform shaped end 23 whereby the wrench l5 may be used as a pry. Inwardly of the end 23 the lever 2i!` is fashioned with a pair of oppositely disposed plane faces 24 adapted for engagement by the jaws of a wrench or other suitable tool.

In use, the parts being in the position illustrated in Figures 1 and 2 of the drawing, the socket is inserted over the sides of a hexagonal shaped nut, the latter forming one of a pair threaded on a shank or the like. The lever 20 is moved longitudinally. a suiiicient distance to permit insertion of the socket 22 over the sides of the other nut constituting the pair. Said barrel is held stationary by a wrench or similar tool engaging the faces of one of the sections i0 and the lever 2B is rotated by means of a wrench or the like engaging the faces 24 whereby the square shaped nut is moved relative to the hexagonal shaped nut. A

Itis to be understood that the lever 20 may be held stationary and the barrel 8 rotated to effect reverse adjustment between the nuts. In instances where it is desired to adjust nuts of different sizes, the head II may be substituted for a similar head adapted to the size of the nut land likewise the lever 20 may be substituted for a similar lever having a head equipped with a different size socket. It will be noted that the lever 20 through the medium of the head 2l thereof coacts to maintain the head Ilin connected relation with the barrel 8. Furthermore, the head II may be disengaged from one end of the barrel and inserted in the opposite end.

From the foregoing it will be apparent that I have provided a simple and eflicient wrench so constructed and arranged as to permit relative adjustment oi a pair of nuts without the use of additional means for securing one of said nuts stationary relative to the other during a desired adjustment.

It is to be distinctly understood that various changes and modifications may be resorted to in the construction and arrangement of the parts without departing from the snirit of the invention or scope o! the appended claims. what I claim is: Y i 1. A device of the character demribed. comprisms, a barrel having a bore fashioned at one end with a toothed conical shaped countersink, a head fashioned with a nut receiving socket and with a' toothed shank detachably carried 'withinsaid countersink and eecting meshing of said teeth whereby said head is rotated by said bar-- rel.` and a readily detachable lever rotatably mounted in said bore and fashioned with a. head Y formed with a nut receiving socket, said last mentioned head rotatably-mounted in said rst mentioned head and adapted to `secure one of e. pair of nutsV for movement relative to the other when the latter is engaged by the socket oi' said first mentioned head and said barreland leversubjected to relative rotation.

`2. A device of the character described, comassises prisma. a barreihaving a bore fashioned at one end with a toothed a head fashioned with a nut receiving socket and with a toothed shank detachably carried within said countersink and effecting meshing of said lteeth whereby said head is rotated by said har-v rel, and ve. readily detachable lever rotatably conical shaped countersink,

mounted in said bore and fashioned with a head eect relative movement of said ban-el and lever.
